AFAM Vent Door Assembly
A microprocessor controlled vent door provides programmable control of the air exchange rate. The vent
door is adjusted to the desired position by a vent door motor and linkage assembly, shown in Figure 14.
The system is pre-calibrated for air exchange rates of 0 to 225 m
3
/hr. (0 to 132 ft
3
/min.). The use of the
AFAM system should be established by the shipper.
The default setting for AFAM in the Setpoint menu is the last value set (Off, AFAM). The Fresh Air Vent
Man submenu should be set to AFAM to control the vent door to the fresh air exchange rate setting.
If the controller identifies a component failure during unit startup, an alarm is recorded in the controller
display and data-logger memory. If a power loss occurs after the AFAM system is turned on, the
controller automatically operates the vent door based on the previous AFAM Delay and AFAM Rate
settings when power is restored.
Advanced Fresh Air Management Plus (AFAM+) System (Optional)
The Advanced Fresh Air Management Plus (AFAM+) System provides programmable control of the CO
2
level in the container. The controller can be set to control the CO
2
level in the container from 0 to 25
percent. See “Advanced Fresh Air Management Plus (AFAM+) System” on page 117 for more
information.
WARNING: After installing or servicing the AFAM door, remove all tools and install the vent
grille before starting the AFAM system. Failure to replace the vent grille before turning the
AFAM system on may result in personal injury or unit damage.
